.PST File Extension

Microsoft Outlook Personal Folder File

Data File
The PST file extension is associated with Microsoft Outlook, an application used for managing personal information included in the Microsoft Office suite. The latest version of the program is Microsoft Outlook 2011 for Mac OS and Microsoft Outlook 2013 for Windows. Commonly used for sending and receiving e-mail messages, Microsoft Outlook also features a journal, task manager, calendar, contact manager and note taking.

Files with the PST extension are data files used by Microsoft Outlook and Microsoft Exchange to store all e-mail information. They’re usually located in â€"App Data\Local\Microsoft\Outlook”. Outlook 2010 stores them in the â€"Outlook Files” folder located in â€"My Documents” or â€"Documents”, depending on Windows version.

PST is an acronym for â€"Personal Storage Table”. Up until Outlook 2002, PST files used ANSI encoding and their maximum size was 2 GB. Starting with Outlook 2003, Microsoft changed the encoding to Unicode which allowed users to define the maximum size of their PST files, up to a limit of 20 GB. The current limit, implemented in Outlook 2010 is 50 GB.

PST files contain all data stored in the e-mail folders of Outlook. This includes e-mail messages, calendar items, e-mail attachments, contacts, RSS Feeds (Outlook 2007+), suggested contacts (Outlook 2010+), Journal, Deleted Items, Sent Items etc.

    Hi Vilas,

    What version of Outlook are you using, 2003? Have a look at the bottom of this Microsoft article (Security settings for .pst files/Passwords).

    Hope that helps :)

    I have a user who wanted to open a pst file with outlook. So he right clicked on the pst file and used open with outlook to do it. Now all pst files are trying to open in outlook if they double click on them.
